In 2010, a Transit Elevated Bus (TEB) concept was made to decongest traffic in China. The concept is a cross between a bus and railways system that allows cars to pass underneath as the bus stops in a station. According to Xinhua News Agency, building the TEB only takes a short time and five times less expensive to manufacture than a subway.

Last May 2016, a miniature model of TEB debuted during the 19th China Beijing International High-Tech Expo. In a recent development, this futuristic bus has made its first test run in Qinhuangdao. With this, engineers and officials aim to raise awareness of TEB's feasibility and answer the public's safety concerns.

The prototype is powered by electric and solar energy, measures 22 meters long, 7.8 meters wide, and 4.8 meters tall. Estimated capacity is rated at 300 passengers features 18 seats along the walls and two round seats placed in the center. Its track covers 300-meter of road.

After the TEB's first run, engineers say it still has its limitations. These limitations include the unpredictablility of traffic below the bus and sharp corners. As development continues, its redesigned version could reach speeds of 60km/h with a capacity up to 1,400 passengers.
